Pre-colonial Igbo political orgnization was based on semiautonomous communities, devoid of kings or governing chiefs. With the exception of towns such as Onitsha, which had kings called Obis, and places like Nriand Arochukwu, which had priest kings known as Ezes, most Igbo village governments were ruled solely by an assembly of the common people. Although titleholders were respected because of their accomplishments, they were never revered as kings, but often performed special functions given to them by such these assemblies.
This way of governing was immensely different from most other communities of Western Africa, and only shared by the Ewe of Ghana. Igbo secret societies also had a ceremonial script called Nsibidi.
In 1966, a failed coup d'etat by Nigerian army officers led by an Igbo, Major Kaduna Nzeogwu resulted in the death of Sir Ahmadu Bello (the Sardauna of sokoto, a prominent northern Nigerian of the Hausa ethnic group). Although the coup was foiled primarily by another Igbo, Johnson Aguiyi-Ironsi, the belief prevailed in northern Nigeria that Hausa leaders were singled out for death.
